I think skepticism is helpful.
I think certain sweeping claims made by the pro-Global Warming people are extreme.
But I can't deny that humans are affecting the earth in ways we never have in the history of mankind.
My real problem is this:
Say you have one scientist that says "the world is round".
You have another scientist that says "the world is flat".
Journalists and others will say, "Well, we need to give a fair amount of time to hear both sides of the argument." (In fact that is a common phrase FOX News broadcasters use when being accused of lying or employing questionable journalistic practices or broadcasting poorly researched half-truths.)
My personal opinion is, "No, we don't have to hear both sides in the instance where one side is clearly lying. One is right and the other is clearly lying."
Maybe that is the wrong opinion to have, but that's how I feel.
